Hang at boot on KVM: attimer problem ?

[Emmanuel Kasper <emmanuel%libera.cc@localhost>]

Hello

I noticed that my NetBSD hosted on a KVM provider the system hangs at
reboot after printing the following line:

attimer0: attached to pcppi0

( screenshot of the virtual console here: http://i.imgur.com/5lLyf.png)

Doing a reset from the control interface solves the problem.

The downside is that I can't simply type "reboot" to bring the machine up.

What could be the cause of the problem ?
